Description
Technical field
The utility model belongs to oil extraction apparatus field, especially relates to a kind of replaceable pipeline antiscale wax control work
Tool.
Background technique
Generally all contain wax in crude oil, there is the very high oil field of many paraffin contents in China, and in oil producing operation, crude oil is from underground
To during ground since temperature constantly reduces, the meeting after temperature reaches wax precipitation point (generally at 40 DEG C or so) of the wax in crude oil
It is precipitated and is condensed on sucker rod and tube wall, eventually lead to oil pumping operation stopping, it is necessary to which the wax of solidification is removed just by " well-flushing "
It can continue to pump, Paraffin Removal becomes the important technical links of crude oil production；The most common method of well-flushing is hot wash or paraffin removing with chemical method,
This is no doubt effective, but must stop oil producing operation and can just restart oil pumping operation after undergoing the drainage period of a couple of days, has simultaneously
The discharge of a large amount of chemical substances seriously affects crude oil production efficiency and pollution environment.
Pipeline type special type metastable alloy antiscale wax control tool in the prior art is welded using many places, is unfavorable for replacing metastable
Alloy mandrel.
Summary of the invention
The utility model provides a kind of replaceable pipeline antiscale wax control tool, solves the above technical problem.
Purpose of the utility model is realized as follows: a kind of replaceable pipeline antiscale wax control tool, it is characterised in that: packet
Containing multiple metastable alloy mandrels, the metastable alloy mandrel is connected with gland, the Asia by bolt, nut left and right ends
Steady alloy mandrel, gland are arranged in first sleeve, and the first sleeve outer surface is enclosed with second sleeve, and described second
Sleeve left and right ends are welded with flange；The left and right two that retaining ring is stuck in second sleeve is provided at left and right sides of the first sleeve
End；The gland is composed of the first gland and the second gland, and the joint face of first gland and the second gland is adopted
With ladder connection, first gland is connected as one with the second gland by multiple positioning bolts.
The retaining ring and second sleeve uses welding connecting mode.
Second gland is uniformly arranged there are six counterbore matched with positioning bolt, and second gland is uniformly set
It is equipped with metastable alloy mandrel mounting hole；First gland is provided with thread groove matched with positioning bolt.
The positioning bolt uses stainless steel material.
The internal diameter of the retaining ring is set as D, and the outer diameter of first gland is set as d, the D < d.
The gland of the utility model is composed of the first gland and the second gland, first gland and the second gland
Joint face using staged connect, it is ensured that the sealed environment in second sleeve；First gland and the second gland pass through multiple positioning
It is bolted and is integrated, metastable alloy mandrel can be taken out by unclamping positioning bolt, repair maintenance or replacement.
